With a maximum flow rate of \u003cstrong\u003e4.5 m³ per hour\u003c\/strong\u003e and a filter tank with a diameter of 350 mm, this sand filter is perfectly suited for private above-ground and in-ground pools with a volume of up to approximately \u003cstrong\u003e16 m³ (16,000 litres)\u003c\/strong\u003e. \u003c\/p\u003e\n\u003cp\u003eThe filter tank is manufactured from sturdy \u003cstrong\u003epolyethylene (PE\/HDPE)\u003c\/strong\u003e. This plastic material is particularly suitable for swimming pool installations thanks to its excellent resistance to moisture, weather conditions, and the pressure that builds up in the tank during the filtration process. This makes the W’eau HDPE-350 a solid foundation for a durable pool installation.\u003c\/p\u003e\n\u003ch2\u003eEffective filtration of swimming pool water\u003c\/h2\u003e\n\u003cp\u003eGood water circulation and filtration are essential for clear pool water. During filtration, the pool pump pumps water from the pool to the W’eau HDPE-350. The water is then guided through the filter medium in the filter tank.\u003c\/p\u003e\n\u003cp\u003eDirt particles are trapped by the filter material, after which the filtered water is returned to the pool. The HDPE-350 has a filtration fineness of approximately \u003cstrong\u003e25 to 30 microns\u003c\/strong\u003e, which filters small dirt particles, among other things, out of the pool water. \u003c\/p\u003e\n\u003cp\u003eThe sand filter therefore continuously helps to remove contamination that would otherwise remain floating in the pool water. In combination with the correct water treatment, this helps to keep the pool water clear and pleasant throughout the swimming season.\u003c\/p\u003e\n\u003ch2\u003eCapacity of 4.5 m³ per hour\u003c\/h2\u003e\n\u003cp\u003eThe W’eau HDPE-350 has a maximum flow rate of \u003cstrong\u003e4.5 m³\/h\u003c\/strong\u003e, or approximately 4,500 litres of water per hour. The sand filter is suitable for pools up to a maximum of approximately \u003cstrong\u003e16,000 litres\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt is important that the connected pool pump matches the capacity of the sand filter. A pump that is too powerful can force water through the filter medium too quickly, which may make filtration less effective and increase the load on the filter tank.\u003c\/p\u003e\n\u003ch2\u003eSpace-saving Top Mount design\u003c\/h2\u003e\n\u003cp\u003eThe HDPE-350 is designed as a \u003cstrong\u003eTop Mount sand filter\u003c\/strong\u003e. This means that the 6-way valve is mounted on top of the filter tank.\u003c\/p\u003e\n\u003cp\u003eThe great advantage of this is a compact installation. With a Side Mount sand filter, the valve is located next to the filter tank, requiring more space around the tank. With the HDPE-350, the entire installation remains relatively narrow, making it ideal for placement in a technical room, garden shed, or compact pool setup.\u003c\/p\u003e\n\u003cp\u003eWith a diameter of approximately \u003cstrong\u003e350 mm\u003c\/strong\u003e and a height of about \u003cstrong\u003e750 mm\u003c\/strong\u003e, the filter takes up relatively little space. \u003c\/p\u003e\n\u003ch2\u003ePractical 6-way valve\u003c\/h2\u003e\n\u003cp\u003eThe W’eau HDPE-350 features a multi-functional \u003cstrong\u003e6-way valve\u003c\/strong\u003e. This allows you to easily control how the pool water is directed through the installation.\u003c\/p\u003e\n\u003cp\u003eThe six positions are:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFilter:\u003c\/strong\u003e the standard operating mode. Pool water is passed through the filter medium and then returned clean to the pool.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBackwash:\u003c\/strong\u003e this reverses the water flow through the filter medium. Accumulated dirt is loosened from the filter bed and removed via the drain.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRinse:\u003c\/strong\u003e used after backwashing to properly re-position the filter medium and flush out any remaining dirt through the drain.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWaste:\u003c\/strong\u003e pool water is led directly to the drain without passing through the filter medium. Useful when you want to lower the water level, for example.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCirculate:\u003c\/strong\u003e water circulates through the installation without passing through the filter medium.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eClosed:\u003c\/strong\u003e shuts off the water flow through the 6-way valve.\u003c\/p\u003e\n\u003cp\u003eAlways switch off the pump before changing the position of the 6-way valve.\u003c\/p\u003e\n\u003ch2\u003eEasy cleaning through backwashing\u003c\/h2\u003e\n\u003cp\u003eA major advantage of a sand filter compared to many cartridge filters is its simple maintenance. The filter medium does not need to be removed from the filter and cleaned manually every time.\u003c\/p\u003e\n\u003cp\u003eWhen the pressure in the filter tank increases or the water flow noticeably decreases, the filter can be cleaned using the \u003cstrong\u003eBackwash function\u003c\/strong\u003e. The water then flows in the opposite direction through the filter bed and discharges the accumulated dirt.\u003c\/p\u003e\n\u003cp\u003eAfter backwashing, use the Rinse setting briefly before setting the installation back to Filter.\u003c\/p\u003e\n\u003ch2\u003eChoice of various filter media\u003c\/h2\u003e\n\u003cp\u003eThe filter tank has room for approximately \u003cstrong\u003e25 kg of filter material\u003c\/strong\u003e. When using traditional filter sand, about \u003cstrong\u003e25 kg of fine filter sand\u003c\/strong\u003e is required. For filter glass, a smaller amount is needed due to different material properties; for the comparable W’eau 350 filter, approximately \u003cstrong\u003e21–21.3 kg of fine filter glass\u003c\/strong\u003e is specified. \u003c\/p\u003e\n\u003cp\u003eFilter glass is an interesting alternative to traditional filter sand. It has a long lifespan and can offer very good filtration depending on the product used. Always pay attention to the prescribed grain size and quantity of the chosen filter medium when filling.\u003c\/p\u003e\n\u003ch2\u003eSturdy polyethylene filter tank\u003c\/h2\u003e\n\u003cp\u003eThe filter tank of the HDPE-350 is manufactured from \u003cstrong\u003epolyethylene\u003c\/strong\u003e. The great advantage of plastic is that it cannot rust and is perfectly suited for a humid swimming pool environment. Furthermore, the material is resistant to normal weather influences and the pressure load that occurs during filtration. \u003c\/p\u003e\n\u003cp\u003eThis makes the HDPE-350 a good choice for those looking for a solid filter tank without opting directly for a heavier, polyester-reinforced model.\u003c\/p\u003e\n\u003ch2\u003e50 mm connections\u003c\/h2\u003e\n\u003cp\u003eThe W’eau HDPE-350 features a standard \u003cstrong\u003e50 mm connection\u003c\/strong\u003e. This allows the sand filter to be easily integrated into many permanent pool installations with 50 mm PVC piping. \u003c\/p\u003e\n\u003cp\u003eFor pools using flexible 32 or 38 mm pool hoses, suitable adapters or hose couplings may be required depending on the installation.\u003c\/p\u003e\n\u003ch2\u003eSuitable for above-ground and in-ground pools\u003c\/h2\u003e\n\u003cp\u003eThanks to its compact size and capacity, the HDPE-350 is versatile. The sand filter can be used for both \u003cstrong\u003eabove-ground pools and smaller in-ground pools\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eEspecially for pools up to approximately 16,000 litres, the HDPE-350 offers a great combination of capacity, compact dimensions, and ease of use.\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003c\/p\u003e\n\u003ch3\u003eCompact sand filter for reliably clear pool water\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eW’eau HDPE-350 Top Mount sand filter 4.5 m³\/h\u003c\/strong\u003e is an especially strong choice if you are looking for a compact and user-friendly sand filter for a smaller pool.
